The design of common path makes the measurement beam and the reference beam incident on the surface along the same way.

共光路设计， 使测量光和参考光沿同一路径入射到被测表面上。

The analysis is made based on the reciprocity of object beam with reference beam and experimental results are presented in this paper.

本文用物光、参考光地位对等的观点来进行分析，并给出了实验结果。

The results show that diffraction efficiency of a lossless grating increases with the higher ratio of reference beam width to object beam width.

对于无吸收的光栅，参考光束相对物光束越宽，衍射效率将越高。

The page of bits is read by aiming the reference beam at the given location.

FORBES: Deep Storage

When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.

Then this is applied to the holographic memory, which contains transformed target images, each written into the memory using a different reference beam.
